Meteor Client 1.21.1- 1.20.6 -- 1.16.5 !!hot!! May 2026

Meteor Client is a popular Fabric-based utility mod for Minecraft. It is primarily developed for the latest stable versions of the game, but archives exist for older versions. Version Compatibility Report Minecraft Version Meteor Client Release 1.21.1 0.5.8 The standard release for this version. 1.20.6 0.5.7 Stable version for the 1.20.6 update. 1.16.5 0.4.4 Often referred to as part of the 1.16.x "legacy" builds. Core Features

Across these versions, the client provides a wide array of utility and "hacked" modules accessible via the Right Shift key.

Combat: Includes Crystal Aura for automated end crystal attacks, Kill Aura for nearby entities, and Auto Totem to automatically equip Totems of Undying.

World & Movement: Features like X-Ray for locating ores, Flight, and Speed Mine to break blocks faster.

Player Utility: Tools such as Auto Trap to build obsidian boxes around players and Ghost Hand to interact with containers through walls. Technical Requirements ManInMyVan/meteor-archive - GitHub

Developing a "piece" or custom module for the Meteor Client requires using its official Addon Template, which streamlines the setup for multiple Minecraft versions. 1. Getting Started with the Template

The easiest way to start is by cloning the Meteor Addon Template on GitHub. This repository is specifically designed for developers to build modular extensions for the client. Meteor Client 1.21.1- 1.20.6 -- 1.16.5

Clone the Repository:git clone https://github.com/MeteorDevelopment/meteor-addon-template my-addon

Open in IDE: Import the folder into IntelliJ IDEA or VS Code as a Gradle project.

Update the Version: In your gradle.properties file, update the minecraft_version to match your target (e.g., 1.21.1 or 1.16.5). 2. Development Essentials

To create a functioning module, you must register it within your addon's main class:

Modules: Extend the Module class to create custom cheats or utilities (e.g., a custom "Auto-Leave" or enhanced "KillAura").

Starscript: If your piece involves dynamic HUD elements, use Starscript, Meteor's custom scripting language for text and data display. Meteor Client is a popular Fabric-based utility mod

Commands: Extend Command to add custom chat-based triggers for your module settings. 3. Compatibility Across Versions

Because Minecraft’s code (Yarn mappings) changes significantly between versions like 1.16.5 and 1.21.1, you will likely need separate branches for each:

1.21.1 & 1.20.6: These versions use the latest Meteor API. Refer to the current Meteor Client GitHub for the most recent class structures.

1.16.5: This version is considered "legacy" in the Meteor ecosystem. You may need to reference the Meteor Archive for older jar versions (specifically version 0.4.4 or earlier) and their corresponding mapping dependencies. 4. Recommended Community Examples

If you need inspiration or code snippets to see how others "piece" together modules, check out popular open-source addons:

Meteor Rejects: A collection of modules not included in the main build. AutoMine – Mines targeted block while moving around

Vector Addon: A powerful open-source example for advanced movement and PvP.

Trouser-Streak: Often used on anarchy servers for specialized world-griefing tools.

Part 6: Safety, Bans, and Ethics

Before downloading Meteor Client 1.21.1-1.20.6--1.16.5, you must understand the risks.

Utility / Automation

AutoMine – Mines targeted block while moving around obstacles.
AutoFarm – Harvests and replants crops (works with 1.16–1.21 crop changes).
AutoFish – AFK fishing with auto-recast.
Baritone integration – Pathfinding automation (dig to coordinates, build schematics). Meteor bundles Baritone.

For 1.21.1, 1.20.6

Download and install Fabric: Ensure you have Fabric installed on your Minecraft instance. You can download it from the official Fabric website.
Download Meteor Client: Get the Meteor Client mod from the official GitHub repository or a trusted source.
Install Meteor Client: Place the Meteor Client jar file in your .minecraft/mods directory.

Performance tuning

Lower render distances and disable expensive render modules (chams, full XRay) to reduce CPU/GPU load.
Use “tick limit” or event throttling options (if present) to reduce how frequently heavy modules run.
Allocate reasonable RAM for the game—avoid excessive allocation which can worsen GC pauses.
Update graphics drivers and Java runtime when running newer Minecraft versions.

What’s New in 1.21.1?

Meteor Client 1.21.1 is the latest stable branch for modern Minecraft. If you are playing on current-gen anarchy servers or testing new combat snapshots, this is your version.

Key Features in this build:

Auto-Crafting 2.0: Fully compatible with the new crafters introduced in 1.21.
New Armor Trims Bypass: Many anti-cheat patches have been updated to ignore visual trims.
Improved Packet Fly: Exploits the 1.21.1 network protocol for smoother flight on laggy servers.
Tweak to TNT Mechanics: Updated logic for TNT duping in 1.21.1 redstone-heavy servers.

1.21 – 1.21.1

Trial spawners – Meteor’s AutoMine can break them (but they drop less without ominous bottle).
AutoLoot works on vaults and trial spawners.
Breeze rods – AutoFarm doesn’t help (breeze not farmable), but KillAura targets breezes efficiently.
Mace weapon – AutoMine doesn’t use mace, but Criticals module can trigger mace’s density enchantment fall damage.
No major anti-cheat bypass changes – most 1.20 exploits still work.

Part 4: Version Comparison Table

1.19 – 1.19.4

Warden detection – Meteor added AntiWarden (prevents shrieker activation) and NoVibration (ignores sculk vibrations).
Swift Sneak – Meteor’s Speed module can stack with swift sneak for insane crouch speed.
Chat reporting – Meteor bypasses chat signing by sending unsigned chat packets (works on 1.19.1+ but risk of server-side filtering).
